Mass Hysteria Card Review

It’s a very interesting card. For 5 mana, you will often get a full board clear, which is not something a Priest can do with other tools, such as Holy Nova. Right now, the card’s usage might be limited, because most of the slower Priest builds still run a Dragon core with Duskbreaker, but the card is going to rotate out soon.

The great thing about this card is that it works well against both wide and tall boards. If your opponent has a bunch of small minions, them attacking each other most likely means that everything dies. But if your opponent has only two big minions, you can also use it in a way Supercollider would work, to force them to attack each other. Of course, you having minions kind of messes up with it, but let’s be honest – if you’re playing a Control Priest, the chances are that you have no board anyway.

Now, the problem is when your opponent has a mixed board, with some big and some small minions. Then, sadly, the card will heavily rely on RNG to clear the board. That’s the part I dislike – on many board states (e.g. Even Shaman with a bunch of Totems and a few minions, or Even Paladin with two midrange minions and two 1/1’s), the outcome will be either a full board clear or the card will do almost nothing depending on how lucky/unlucky you get. Yes, there will still be a skill in identifying those kind of board states and trying to not play it then, but sometimes you just don’t have a choice. That’s why I think that Brawl is a stronger card in general. It’s just more consistent – no matter what the board state is, you can always clearly see the worst outcome – the biggest minion on the opponent’s side survives – and try to prepare for it. You will always have a single minion surviving, but in this case, on a more complicated board states, you basically have no idea what is going to happen. But

I think that even if not right now, the card will see quite a lot of play after the rotation happens. Psychic Scream is absolutely amazing, but Turn 7 is often too late – Aggro and Midrange decks can kill you by that time if you don’t clear the board earlier. And let’s be honest, Holy Nova doesn’t really cut it when lots of minions have 3 health. This, while not exactly most consistent in some matchups, will probably be the best option anyway. But I think that this kind of effect is hard to theorycraft about, we’ll just need to wait and see how it works in practice.

So, say you are on turn 10 and fill the board with minions for 5 and then play this. Will you be able to have your minions attack the turn they are played, without charge or rush? (random targets, but who cares)

This card is just so OP. It is probably left as another “duskbreaker” for priest after it rotates. Because the description says “another minion”. So versus aggro, you could have an empty board and then use this and watch your opponent’s high attack, low health minions killing each other.

Oh, and if your opponent mainly has low attack, high health minions(taunt druid), you can just play void ripper/confuse and then clear the entire board. In some situations it is actually better than dragonfire because it can clear dragons and deal more damage. It is also better than brawl because this could technically be a twisting nether

Ok let make this simpler
2 scenarios
# 1) 3 3/3 wolfs/ wolf #1 attacks wolf #2 wolf 1 &2 die (if damage happens at the same time) wolf 3 still must attack a minion and would attack wolf 1 or 2 even though both are not really their because they killed each other and all 3 die.
#2) 2 8/8 and a boar/ 8/8 #1 attacks boar 8/8 lives boar dies (if damage happens at the same time) 8/8 #2 still must attack a minion and could attack the boar even though it is not really their because it was killed so you can end up with one 8/7 and one 8/6 as the boar still must attack also.
So, in some scenarios you can still end up with big things on the board if you get unluck.
I am not saying that makes this a bad card per say you just got to watch when you use it.

due to 5 mana its a super good cards.this card can be so nasty.
mb its not like brawl but brawl wont give u a clear board.this one can and its very good against aggro or control.
i guess of the best removal in game its is very good against cancer shaman or paladin.
but priest geting crazy in wild.
i cant wait for next expansion .saved a lot of gold for it and 4k dust already.yummmyyyyy

Wait . . . “Force EACH minion to attack another.” Does this only count the attack if the minion initiates it, rather than receives it? i.e., if there are two Obsidian Statues in play, do they just hit each other and each take four damage, or does the first attack the second AND THEN the second attacks the first, killing them both?

from how I am reading this card it is possible to have 1 minions cleared with this card lets say you playing an opponent that has all 8/8 on there side besides a stone tusk boar it is possible for everyone of their minions to all hit the boar meaning you just paid 6 mana for a whiplash that so this is a more come from behind card as it works best on a board where you have little to no minions and you opponent has lost of minions that will kill each other

no as all attack are happing at the same time same reason arcane missiles will not kill a Jo-E Bot if the 1 shot hits Mecharoo it is the same reason why if there are 3 wolfs on the board off a emerald spellstone and nothing else on the board and you cast this all 3 will die

Well ok, this card is fairly mad take on brawl… but I really like the flavour.

As a straight up 5 mana board clear it’s clearly weaker than a lot of comparable cards. But it will also have some decent advantages in certain situations, such as where only two cards are in play you can be certain of the outcome. Also against swarm decks that have equally statted minions, e.g. paladin, this will be effective.

Standalone then its power is far from OP and nothing like the old dragon potion, however giving priest another form of board clear/management between duskbreaker and psychic scream will probably be great for control or combo priest decks. The effect also requires players to think, which is great, and occasionally just pray to the RNG. A bit of a downside that it doesn’t synergise with the loa in play, but it does synergise with the slower value style of play of the loa deck which is good.

Probably a 3/5 card if not 2/5 card, but one which could see a lot of play by better enabling slower priest decks.

This might as well be a Brawl for priest. I don’t like brainless board clears that benefit from not playing any minions, but I guess they thought they needed a new year’s follow up to Psychic Scream. This will absolutely see play.

Curious if this will activate Overkill effects for your opponent’s minions. It’d be nice if it does- opens up some fun counterplay.
